Hypothyroidism is a condition in which the thyroid gland is not producing the thyroid hormones adequately. This is a fairly common condition.

What is thyroid gland?

The thyroid gland is a small butterfly-shaped gland located just below Adam s apple. It encircles the windpipe or the trachea. It is about 4 cms in height and weighs about 18 gms. This gland is responsible for the secretion of thyroid hormones. Hormones are chemicals produced by special glands like thyroid, adrenals, ovaries etc. They act as messengers and are carried by the blood to the various target organs.

What are the hormones produced by thyroid gland and what do they do?

The thyroid hormones are of two types   T3 (Tri iodo thyronine) and T4 (Thyroxine). These hormones are mainly responsible for the body s metabolism - a process in which food is converted into energy in the cells. They influence growth and development and regulate various bodily functions which are mentioned below:

Heartbeat
Body temperature
Breathing
Body weight
Metabolism of fat
Menstrual cycles in females
Functioning of Nervous system
Digestion
Burning calories etc.
What is Hypothyroidism?

Inadequate production of hormones by the thyroid gland is termed as hypothyroidism. This is also called Underactive thyroid state. Hypothyroidism can make the body s development to slow down and reduces metabolism rates.

What are the causes of Hypothyroidism?

Hypothyroidism can be caused by a number of factors:

Hashimoto's thyroiditis: This is the commonest cause. This is an autoimmune disorder (normally body s defence system fight against external infections. In autoimmune disorder the defence system attacks the healthy cells of the body by mistake). In Hashimoto s thyroiditis the immune system/defence system produces antibodies that attack the thyroid gland and destroy it.
Iodine deficiency in diet. For the production of thyroid hormones iodine is very important. The body does not produce iodine normally, so it needs to be supplemented from outside. Iodine is mainly present in the food we eat. It is mainly present in shellfish, salt-water fish, eggs, dairy products. If a person does not eat iodine rich foods, he may end up with iodine deficiency leading to hypothyroidism. Currently, this causative factor is on the decline due to government initiative of table salt with iodine.
Surgery: Surgery to remove thyroid gland (for e.g. thyroid cancer treatment, overactive thyroid etc.)
Radiation to the neck (to treat cancer in the neck area): The thyroid gland cells are damaged due to the radiation.
Treatment with radioactive iodine: This treatment is used for managing hyperthyroidism/overactive thyroid, where the thyroid gland produces excessive thyroid hormones. One of the treatment modalities is by radioactive iodine. Sometimes this radiotherapy destroys normal functioning cells which lead to hypothyroidism.
Certain medicines: Certain medicines used to treat heart conditions, cancer, psychiatric conditions etc.   for e.g. amiodarone, lithium, interleukin-2, interferon-alpha.
Pregnancy: Pregnancy (the reason is unclear but it has been noticed that the thyroid may get inflamed after delivery   this is called Postpartum thyroiditis.
Damage to the pituitary gland: Pituitary gland is a gland which is present in the brain. It produces a hormone called TSH (Thyroxine-Stimulating hormone).The TSH tells the thyroid gland how much thyroid hormone it should make. If the levels of thyroid hormone in the blood are low, then the TSH will stimulate the thyroid gland to produce more Thyroid hormone.
Hypothalamus disorders: This is an organ in the brain. This produces a hormone called TRH (Thyrotropin Releasing Hormone) which acts on the Pituitary gland to secrete TSH. So any disorder of Pituitary gland will indirectly effect the production and secretion of Thyroid hormones. These are very rare disorders.
Congenital thyroid defects: Some babies are born with thyroid problems. This is due to the thyroid not being developed normally during pregnancy. Sometimes the thyroid gland does not function normal. This can be identified by screening for thyroid disorders in the first week after delivery. This is usually by a blood test using a small drop of blood from the baby s heel.
What are the different types of hypothyroidism?

One classification is based on whether the defect is with the thyroid gland or not:

Primary hypothyroidism: The problem is in the thyroid gland itself and thus there is reduced production /secretion of thyroid hormones.
Secondary hypothyroidism: Here the problem is with the Pituitary gland or the Hypothalamus. This results in abnormal production of TSH or TRH, which indirectly leads to less production and secretion of thyroid hormones.
Another classification is based on the symptoms and levels of the thyroid hormones and TSH:

Overt hypothyroidism: Here the patient is having the symptoms. Further the T3/T4 are low and TSH is high
Subclinical hypothyroidism: Here patient may or may not have symptoms. The T3/T4 levels are normal but TSH is high. In this situation the patient is at an increased risk of developing overt hypothyroidism in the future especially if he has Thyroid peroxidase antibodies on testing.
Who are at risk of developing Hypothyroidism?

Women have a higher risk of suffering from hypothyroidism than men.
Older people are at increased risk.
People suffering from other autoimmune diseases like Coeliac disease, Type-1 Diabetes Mellitus, Vitiligo, Pernicious anemia, Multiple sclerosis, Rheumatoid arthritis, Addison s disease etc.
People with psychiatric conditions such as bipolar disorder
People with Chromosomal abnormalities like Down syndrome, Turners syndrome also have a high risk of suffering from hypothyroidism.
What are the symptoms of hypothyroidism?

Symptoms vary from person to person. They may also mimic other conditions and hence be difficult to diagnose. Symptoms may also develop very slowly over a span of moths-years. Some of the characteristic symptoms of this disease are:

Depression
Constipation
Hair loss
Dry hair
Dryness of the skin
Tiredness
Body pains
Fluid retention in the body
Irregular menstrual cycle
Increased sensitivity to cold
Reduced heart rate
Increase in size of the thyroid gland   called Goitre. This is due to constant stimulation of the thyroid gland by TSH.
Weight gain
Carpal tunnel syndrome
Hoarse voice
Infertility
Loss of libido/sex drive
Confusion or memory problems especially in the elderly
What are the symptoms to look for in a baby if you suspect hypothyroidism?

Infants suffering from congenital hypothyroidism may show no symptoms or exhibit signs of excessive drowsiness, cold hands, cold feet, constipation, hoarse cry, poor growth or absent growth, poor appetite, bloating of abdomen, puffiness of face, swollen tongue, persistent jaundice.

How to diagnose hypothyroidism?

Blood tests:

TSH: This hormone is made in the pituitary gland and it stimulates the thyroid gland to produce thyroxine. If the thyroxine levels are low in the blood, the pituitary gland produces and secretes more TSH into the blood to act on the thyroid gland to produce more thyroxine. A raised TSH level indicates hypothyroidism. Other tests are not usually necessary unless a rare cause of hypothyroidism.
T4: A low level of thyroxine indicates hypothyroidism.
T3: these levels are generally not needed to diagnose hypothyroidism
Anti-Thyroid peroxidase antibodies (anti-TPO antibodies) or Anti- thyroglobulin antibodies are present in 90-95% of patient with autoimmune thyroiditis.
Other blood tests include Creatinine Kinase, Serum Lipids, Complete blood picture etc.
Ultrasound of the neck is done if the patient presents with a thyroid swelling.
What is the treatment of hypothyroidism?

Overt hypothyroidism is treated by synthetic Thyroxin hormone which should be taken every day on an empty stomach at least 30   45 minutes before breakfast. The treatment is continued for the rest of the patient s life. Regular thyroid function tests are done once every 8 weeks-12 weeks to adjust the dose of the thyroxine in the initial period of diagnosis. Once the thyroxine dose is stabilised, the tests can be done even once a year. This treatment is quite effective.

Sub-clinical hypothyroidism is only treated if the patient is a woman and is contemplating pregnancy, in patients with symptoms or if the TSH is quite high.

What are the side-effects of thyroxine medication?

There are few side effects if any. Most people tolerate these medications quite well. An important consideration before starting medication is to check if the patient has chest pain/angina. These people are started on the least available dose. If these patients are started on a higher dose they notice a worsening of their angina pains.

Side effects mainly occur if the thyroxine dose is high which leads to hyperthyroidism. The symptoms of this could be palpitations 9increased heart beat), weight loss, profuse sweating, anxiety, irritability etc.

There are some tablets which increase with thyroxine tablets. These include carbamazepine, iron supplements, calcium supplements, rifampicin, phenytoin, warfarin etc.

What are the complications of hypothyroidism?

If untreated hypothyroidism can lead to:

heart problems like heart attack due to increased levels of bad cholesterol like LDL, or heart failure due to fluid retention
obesity
infertility
joint pains
depression
A pregnant woman with hypothyroidism is at increased risk of giving birth to a baby with congenital hypothyroidism, also known as cretinism. Further, the woman may have pregnancy related complications like pre-eclampsia, premature delivery, low birth weight baby, anemia, post-partum haemorrhage (bleeding after delivery) etc.
Myxoedema is another complication where the patient has extremely low levels of thyroid hormone. The body temperature drops drastically making the person lose consciousness or go into a coma.

Know Everything About Hypothyroidism

Eczema is a common skin problem that appears as red, raised rashes on the skin, commonly the face, neck, elbows, hands, and feet. Considered as an allergic response, it is often seen in people who have a predisposition to other allergies like asthma, hay fever, hives, etc.

The good news is that these have identified patterns, and there are things that can be easily done which can prevent flare-ups.

Reduce soap: Soaps are known to dry the skin up and irritate the skin, so eczema flare-up is common in those who love to lather themselves up. If possible, switch to soap or body wash that contains moisturizer as reduce the bacterial load on the skin. People who live in hot and humid locations, such as Mumbai it is important that they cleanse their face completely, else it can lead eczema eruption. 
Moisturize: Keep a moisturizer handy at all times. Eczema is common when the skin is dry, so keep applying moisturizer at regular intervals and keep eczema at bay. Make it a habit to apply moisturizer soon after the bath. The moist skin soaks it in nicely and provides maximum benefit when applied this way.
Avoid artificial fragrances: While deodorants and skin care creams which contain fragrances smell appealing, they also cause irritation and are harsh on the skin. This exacerbates eczema, and so avoiding these products is advised.
Know your trigger: This could be anything from a dishwasher liquid to a bath soap or a deodorant to some plant in your garden. Over a period of time, you will be able to identify the trigger, and avoid it so that eczema does not flare up. Remember, it is a type of allergy after all.
Detergents for washing clothes: Using milder detergents, especially for undergarments, greatly helps. Also, wash these twice to get rid of all the soap. Avoid fabric softeners as they are fragrant and can cause irritation.
Avoid hot baths: While a hot bath at the end of a long day sounds very relaxing, it also leaves your skin dry. This can worsen the condition of eczema. Add to this the irritation from your bedspread and pillow covers. Unless you have the habit of applying copious amounts of moisturizer before going to sleep.
Cover up your hands and face: When possible, use gloves and a mask especially when washing dishes and using laundry detergents. This way, you can prevent dryness and irritation of the skin on the hands and prevent eczema.
Soak it in the tub: When you stay for about 20 minutes in a tub (no hot water though, but lukewarm), the skin absorbs moisture which prevents it from drying. This greatly helps prevent eczema.
Cut down stress: Like any allergy, eczema acts up when stressed, so manage it. There is no point stressing anyways!

This is an issue that is addressed and treated appropriately by homeopathic medication so that the allergy causing elements may be treated and removed accordingly, even as the immunity is strengthened. This makes homeopathy an effective form of treatment for this condition.

Graphites- This homeopathic medication is used when the symptoms include constipation along with changes in the physical appearance of the skin, which becomes rough and hard.

Mezereum- This medicine is most effective when a crust like formation can be seen around the boils. The medicine is also useful when there is accumulation of pus under the crust.

Sulphur- Many patients suffering from atopic dermatitis complain of intense pain along with a burning and itching sensation, which they cannot seem to contain. This medicine usually helps such kinds of symptoms by soothing the affected area.

Dulcamara- This medicine is most useful if and when the condition becomes worse due to a cold and damp weather, in which case the boils may flare up and lead to the oozing of pus and lots of itching.

What Causes Eczema? Ways to Prevent Eczema Outbreaks

A skin inflammation, eczema, also known as atopic eczema, refers to the changes that occur in the upper skin layer. These skin changes can be thickened and cracked skin, skin redness, crusting of the affected area and swollen raw skin, among others. The exact cause of this skin condition is not yet known but a mix of factors have been found to be behind this health problem.

CAUSES :

The factors that play a role in causing eczema are:

- Dry skin brings down your skin's ability to fend off irritants as well as allergy causing substances from entering your skin, resulting in an inflammatory condition.

- Genetics is also one of the factors that may affect the proper functioning of your skin as a barrier against harmful substances. Therefore, if either one of the parent or both suffers from the condition, it is very likely that their children too will suffer from it.

- Abnormal functioning of your body's immune system can also lead to this skin condition. This is because it's your body's immune system that fights off infections as well as harmful intruders.

- The presence of the bacteria called Staphylococcus aureus, which brings about sweat buildup, inflames the skin considerably, leading to this condition.

- Even environmental factors like pollen, cigarette smoke lead to the flaring of eczema.

How can you prevent an eczema outbreak?

It is very common for this skin condition to flare-up from time to time. But you can avoid such outbreaks or reduce their severity by following these very simple ways:

- Keep your skin well-moisturized so that it doesn't dry out causing further irritation.

- Sudden changes in temperature can cause the skin condition to break out. So, when the weather is hot, keep yourself cool but during cold weather, use a humidifier to prevent the skin from drying out.

- Keep sweating in check as it can cause an outbreak very easily

- Avoid the use of harsh detergents and soaps, woolen materials as well as the consumption of foods that may lead to flare-ups
